| Description | The protection mode requested by management for the local
station that can affect the protection status of the RPR
station, according to the set of rules describing the RPR
protection.
When read, this object returns the last command written
unless it has been preempted, or idle if no command has been
written to this interface span since initialization.
There is no pending of commands, that is if a command has
been preempted by a failure, when the failure clears the
command is not executed.
If the command cannot be executed because an equal or \
higher priority request is in effect, an error is returned.
writing idle to a span that has no pending protection
command, has no affect. An idle clears an active WTR state.
The protection commands (arranged in ascending priority
order) are:
idle
This command clears the protection for the specified
interface span.
This value should be returned by a read request when no
protection command has been written to the object.
manualSwitch
A protection command on each end of a specified span. This
command doesn't have precedence over automatic protection,
and therefore it can't preempt
an existing automatic protection request.
forcedSwitch
A command on each end of a specified span. This command has
precedence over automatic protection, and therefore it can
preempt an existing automatic protection request.
Default value of protection command is idle. |
